There are no current plans to support Nutanix Acropolis HyperVisor (AHV). Only current Virtual options are as you mentioned VMWare and Hyper-V, and if you consider hosted then Amazon Web Serivces , AWS just released in Feb. with the new version AM 8.3. There are plans to support Microsoft Azure in a future release, which is where our Access cloud is hosted.

'Not Supported' does not mean it won't work, but the risk is if you find a bug when running on Nutanix Acropolis HyperVisor (AHV), and that bug cannot be reproduced on VMWare or Hyper-V, there will be no commitment from RSA Engineering to try to fix that bug.
